1 Claim. (Cl. 131-10) This invention relates to filters for cigarettes.

An object of the invention is to provide a cigarette filter which is unique in its construction and action.

Briefly, a cigarette filter in accordance with the invention is provided with two distinct filter sections, one containing a group of discs and the other containing a plurality of spaced essentially parallel discs. The filter sections are arranged in tandem with the smoke from the tobacco of the cigarette being required to pass through the group of discs and then pass through the fibrous-type filter group. The filter groups have smoke seasoning chambers between them and it is preferred that a chamber be provided between the disc group and the tobacco.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of a cigarette possessing a filter assembly in accordance with the invention;

FIGURE 2 is a fragmentary enlarged longitudinal sectional view of the cigarette in FIGURE 1;

FIGURE 3 is a sectional View taken on the line 33 of FIGURE 2;

FIGURE 4 is a sectional View taken on the line 4-4 of FIGURE 2; and

FIGURE 5 is a perspective view of one of the discs of the disc filter section.

In the accompanying drawings there is a cigarette 1t) equipped with a filter assembly 12 that is made in accordance with the invention. The cigarette tobacco 14 is conventional, as is the paper wrap-per 16. Filter assembly 12 is formed of a cylindrical filter wall 18 which is preferably paper and which is disposed in the paper wrapper 16 of the cigarette.

There are two filter sections 28 and 22 contained within the Wall 18. The initial section 20 is made of a plurality of parallel discs 24, each spaced slightly from each other and attached at alternate edges to the opposite sides of the wall 18. For instance, disc 24 is attached to the side of wall 18 at the lower part of FIGURE 2, as oriented in the drawings, and the immediately adjacent disc 26 is attached to the opposite portion of wall 18, leaving a small space 28 between the confronting faces of the discs 24 and 26. Discs 24 and 26, and all of the other discs in filter group 20 are smaller in diameter than the wall 18 thereby leaving smoke entrance 30 between one edge of disc 24 and the surface of wall 18; smoke entrance 32 between one edge of disc 26 and wall 18 but on the opposite side of the filter assembly 20 whereby the smoke is required to take a circuitous path in flowing through filter assembly 20.

A smoke chamber 34 consisting of a space between the rear face 36 of tobacco 14 and the initial disc 24, is provided for seasoning the tobacco smoke. Further, the discs in group 20 may be made of several materials, the preferred one of which is charcoal coated aluminum paper or aluminum filmed paper. There is another smoke seasoning chamber 38 between the last disc 27 of filter group 20 and filter group 22. This chamber 38 is defined by the front face of filter group 22 and the confronting face of disc 27.

Filter group 22 is made of a plurality of preferably fibrous filters 40, 42 and '44 each subtending an arc of approximately in cross-section. Filter 44 contains iodine making it brown while filter 40 is alcohol sterilized and is white, and filter 42 is of a color difierent from filters 40 and 44. The medication can vary and may include several commercially available medication preparations. Filters 40, 42 and 44 may be made of cellulose fiber or cotton fiber or hemp fiber. However, it is preferred that filter 44 be made of hemp fibers; filter 40 be made of cotton fibers, and filter 42 be made of cellulose fibers. As shown in FIGURE 2, the filter group 22 is held captive within the cylindrical wall 18 and is recessed inward from the edge 46 of the cigarette paper 16.

In use the smoke from the tobacco first enters chamber 34 and then is required to pass through the circuitous travel around and between the discs of filter section 22. These discs may have small perforations therein or may be imperforate. In either case, the filter enters seasoning chamber 38 and then is required to pass through filter section 22.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation. shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

In a conventionally shaped cigarette which has a wrapper and tobacco, the improvement comprising a cylindrical wall fitted in the cigarette wrapper and containing a first filter section and a second filter section, said first section being spaced from the adjacent face of the tobacco in the cigarette wrapper to thereby provide an initial smoke seasoning chamber in advance of said first filter section, said first filter having a plurality of essentially parallel spaced discs transverse with respect to said cigarette with smoke passages on alternate sides thereof, said discs having a diameter smaller than said cylindrical wall and being attached along a portion of the discs periphery to the cylindrical wall, the discs in said first filter section being constructed of charcoal coated aluminum foil, said second filter section being completely spaced from said first filter section to provide a smoke chamber therebetween, said second filter section being composed of a plurality of fibrous wedge shaped longitudinal segments the apex of each being in alignment with the axis of the cigarette and said segments being of different medicated filter materials.
